XiStrat (aka 'Extended Strategy') is in particular about turn-based, networked multiplayer, non-cooperative, zero-sum, abstract strategy board games (e.g., Chess, Go, Reversi variants, etc.) on 3D-visualized polyhedra and contains a server, client GUI, autoplayer engine, utilities, and documentation. Related recreational modern mathematics (single agent, cellular automata, graph/group/complexity/knot theory, discrete geometry, algebra, combinatorics, and mathematical physics) is also dealt with.
The CoinXtension library is a small extension to the easy-to-use "Coin 3D" graphics framework. It offers some additional operators for the existing data types in Coin 3D, but more importantly it extends the linear algebra capabilities of the original framework by adding the new SbXtMatrix3d data typ. This offers such useful routines as eigenvalues and QR-decomposition. It also provides a SbXtQuaternion class for quaternion representation.
Wykobi is an efficient, robust, and simple to use multi-platform 2D/3D computational geometry library. Wykobi provides a concise, predictable, and deterministic interface for geometric primitives and complex geometric routines using and conforming to the ISO/IEC 14882:2003 C++ language specification. The design and structure of Wykobi lends itself to easy and seamless integration into projects of any scale that require a robust yet efficient 2D/3D computational geometry back-end.
SharpConstruct is an OpenGL graphics application that supports real-time sculpting of polygon meshes. The process is similar to painting on a canvas in a traditional 2D image program, but with an added dimension. Depth is simply brushed onto the model, offering an easy way to create highly detailed meshes.
The Interreality project is a collection of Open Source, Free Software projects based on the Virtual Object System (VOS) platform. The goal is to develop a free and open platform for multi-user 3D virtual reality games, applications, and interactive, collaborative 3D virtual spaces. VOS is a powerful and generic network object framework designed to support a variety of high-performance applications. It is the basis for Ter'Angreal, a general-purpose browser application for entering and participating in 3D worlds.
